They ARE SLICK (and slimy). At SEA-TAC I was selected for a secondary pat down and while I was getting that, and unable to watch my stuff TSA went INTO MY WALLET and took PART of the cash ($200) leaving me to (immediately after the pat down) glance in the wallet, see cash and assume it was all there. After I got to the gate, I sat down and checked that I indeed had everything I came with and discovered the theft. I had just counted it for the trip before leaving the house and there was NO opportunity for it to have been taken anywhere else.
YOU SHOULD NOT BE REQUIRED TO SURRENDER YOUR MONEY AND CREDIT CARDS TO THESE unaccountable PEOPLE'S "CONTROL AND CARE", EVEN FOR A MINUTE. There is no valid excuse for that.
